Extreme Networks Summit 300-24 Hardware Installation Manual page 291

NOTE
The ATM module is a Class 1 laser device.
The default configuration of the A3cSi and A3cMi modules is as follows. Ports 1 and 3:
• Are added to the default VLAN as untagged.
• Inherit the properties of the default VLAN (VLANid and so forth).
For specifications of the A3cSi optical interface, see Table 127 on page 361.
Physical Description
The ATM module (Figure 161) has the following key components:
• Two high-performance network processors
• A GPP subsystem
The network processors are programmable devices that participate with the Extreme "i" chipset to
support expanded functionality, features, and flexibility.
The GPP subsystem handles system control and I/O module management functions. The GPP
subsystem resides outside of the I/O module data path to optimize performance.
